Circa 1996 I was watching “Getting Even with Dad” Starring Macaulay Culkin.
There is a scene at a public aquarium where Macaulay and his father are arguing about a squid, his father insisting that it is a fish. He ask an employee ~ ” A squid is a fish right ? ” ~
The attendant responds in a smug tone “No sir, a squid is a cephalopod”. I thought the word was hilarious so it stuck in my mind.
In 1998 I signed up to the now defunct heat.net to play Total Annihilation online. Unable to find a suitable username I typed in Cephlapod, a rather close approximation of the correct spelling for a 13 year old. I’ve retained it online ever since.
Cephalopod is Latin for Head Foot and denotes class of intelligent molluscs including the squids, octopi and cuttlefish.
